hi
I insert data like this
Calendar calendar = Calendar.getInstance();
calendar.setTime(dateAction);
calendar.set(Calendar.MILLISECOND, 0);
String millis = String.valueOf(calendar.getTimeInMillis());
ColumnPath columnPath = new ColumnPath(columnFamily,
millis.getBytes("UTF-8"), ("showId").getBytes("UTF-8"));
cassandraClient.insert("Keyspace1", userId, columnPath,
showId.getBytes("UTF-8"), timestamp, ConsistencyLevel.ONE);
columnPath = new ColumnPath(columnFamily, millis.getBytes("UTF-8"),
("parentShowId").getBytes("UTF-8"));
cassandraClient.insert("Keyspace1", userId, columnPath,
parentShowId.getBytes("UTF-8"), timestamp, ConsistencyLevel.ONE);
As you can see I use a datetime as super_column name.
I want to make get_slice to get only the showId field. I've tried to make
all the combination to get only this nothing help I get nothing.
like this
col.add("showId".getBytes("UTF-8"));
SlicePredicate predicateNegative = new SlicePredicate(col, new
SliceRange(new byte[0], new byte[0], false, 1000000));
or like this
SlicePredicate predicateNegative = new SlicePredicate(null, new
SliceRange("showId".getBytes(), "showId".getBytes(), false, 1000000));
where is the problem ?
thanks
